INSULATING LUMBER 


INSULATING LUMBER < 


WHAT IT IS 


ELOTEX is the board- 

form insulation that com- 
bines high insulating value with 
structural strength. It is pro- 
duced from cane fibre. It is a 
strong, rigid, waterproofed board, 
having greater strength than 
wood sheathing on the wall, and 
the insulating value of cork. 

There is a use for Celotex in 
every building—as general heat 
and cold insulation, as sheath- 
ing, plaster base, roof insulation, 
interior finish, exterior finish and 
sound deadener. Insulation 
against heat and cold is always 
obtained at the cost of one mate- 
rial. In resisting the passage of 
heat and cold, the 4%-inch thick- 
ness of Celotex is equivalent 
to 1%-inches of lumber, or a 
12-inch wall of concrete. 

To build with Celotex means 
to effect an annual saving of from 
25 to 35 per cent in fuel consump- 
tion; an interior cool in summer 
and warm in winter. To build 
without insulation means to 
futilely attempt to heat all out- 
doors in winter and live in a hot- 
house in sumnier.

Gentlemen: 


In the construction of an 
apartment building for General Felix H. 
Robertson, recently completed at Waco, 
Texas, about 50,000 feet of ‘‘Celotex’’ 
was used, After investigating this 
material, we changed our specifica- 
tions, which originally called for 
metal lath, for we desired to give 
*“Celotex’’ a thorough test as a plaster 
base. 

The owner, as well as our- 
selves, is entirely satisfied with the 
results obtained, and we are pleased to 
report our findings in connection with 
““Celotex’’ as follows: 


First: As a plaster base, 
it proved highly satisfactory, giving 
greater strength than could have been 
obtained through the use of metal or 
wood lath. 

Second: As a sound dead- 
ener and an insulator it is all that 
you claim it to be. 


Third: Its use saved the 
owners approximately $1100.00 in the 
cost of the building. This was not 
anticipated. We would have been satis- 
fied with the use of the material at an 
even greater cost because of its qual- 
ities as a sound deadener and an in- 
sulator. 

We are now specifying 
“Celotex’? and it is our intention to 
continue to do so, for we believe that 
we are serving the best interests of 
our clients thereby.

Attention Mr. C. A. Lindner, 


Centlemen: 


It gives us great pleasure to 
write an unsolicited letter of commenda- 
tion on some of the superior features of 
your product, Celotex, over the heretofore 
more generally used lath and plaster. 


Most important of all, to us, is 
its deadening or sound-proof qualities. As 
you know, the walls of our general office 
ere lined with the Celotex, and the manner 
in which the noises from our pressroom are 
kept out of the office, with only a swing- 
ing door between, is almost unbelievable. 
Our private office is also absolutely 
sound-proof and conversation carried on 
there cannot be heard in the general OoLrfice: 


Tt is also truly remarkable as a 
temperature leveler and retainer. Our of- 
fices remain ideally cool in the summer, 
and in the colder weather are readily 
heated in a few moments and great comfort 
maintained with a very small amount of 
heat. It is often noticeable that our of- 
fices are still warm when we come to work 
in the morning after having been without 
heat since five o’clock of the previous 
evening - a matter of some fourteen hours. 


It is putting it mildly to say 
that we are perfectly satisfied with the 
results obtained from the use of Celotex 
and we wish you great success in the mar- 
keting of so meritorious an article. 


Very truly yours,

Gentlemen: 


You are correct in your information in re. 
my having used "Celotex Insulating Lumber" in the recon- 
struction of a suburban cottage. The facts are, lirs. 
Marfield, in the late summer, purchased a little place 
at Ponchatoula, Louisiana, on which was located a very 
roughly constructed cabin of threo rooms. 


After a visit to your plant, I was immediately 
impressed with the value.of your product, and felt it 
could be used to good advantage in lining the cottage we 
had on our hands. 


After a great deal of persuasion, Urs. Marfield 
consented, and the transformation of the rough cottage into 
@® cozy three room bungalow was so complete within three or 
four days tims, that she was more than delighted with the 
Result, 


It gives me a great deal of pleasure to say that 
I consider Celotex not a coming, but an established product.

It gives us a great deal of pleasure to say @ few 
words regarding Celotex Insulating Lumber, 

Celotex was used as a plaster base on tne Royal Street 
School, Dallas, Texas, and upon completion of the building was 
found to be in splendid condition. 

We have used Celotex for roof insulation, cold storage 
rooms, partition walls and on one job for a ceiling which was 
used for its acoustical value. 

We anticipate using this material quite extensively, 
for in addition to its wonderful insulating value, it makes a 
perfect plaster base. 
Yours very truly,

Gentlemen: 

We have recently fitted up 
new ware rooms at No. 26 South Michigan 
Avenue, and have used in our Talking 
Machine demonstrating rooms, *““Celotex’”’ 
for partitions. 


It gives us pleasure to 
state that we have found this material 
to be highly satisfactory, not only in 
regard to its sound-proof qualities, 
put also from the standpoint of reson- 
ance. It has seemed to us and to our 
customers that the talking machines 
demonstrated in our rooms have an un- 
usually sonorous and resonant quality 
of tone; and we attribute this largely 
+o the fact that the walls of these 
rooms are lined with ‘‘Celotex’’. 


We are pleased to give this 
information to whosoever may wish to 
avail themselves of it, and to extend 
to anyone who may be interested in in- 
vestigating a cordial invitation to 
visit our ware rooms, and to see and 
hear for themselves how satisfactory 
this material has proved to be. 


Aside from the above the 
material itself is of a very pleasing 
texture; so much so that we decided to 
leave it in its natural state, rather 
than to stain or color it artificially. 

Yours very truly,

expericnccd by Brick Manufacturers is roof 
construction for drier houses. These roofs 
are always practically flat and are ex- 
pected to retain heat in the tunnels as 
well as to exclude rain. We have experi- 
nented for a number of years and re-roofed 
our Dry House last year with a patented 
pnaterial guaranteed to retain heat and to 
be impervious to water. This roof was an 
obsolute failure within ninety days after 
its construction. 


Our last experiment consisted in 
treating our roof with a heavy coat of 
filler, then laying a covering of Celotex 
in hot asphalt, covering the Celotex with 
another coat of hot asphalt finished with 
three layer coat of asphalt paper. The 
results obtained have bcen somewhat star- 
tling as we have had to reduce our gas 
under dry house 60% to 70% allowing us to 
operate, since Celotex was applied, with 
30% to 40% of our former gas consumption. 


We believe that we have solved 
the question of drier roof construction for 
brick plants--thanks to Celotex--and this 
is a question of grave importance to all 
prick manufacturers. I honestly believe 
that a roof, such as we have constructed, 
will pay for itself many times from saving 
in fuel alone and, at the same time, re- 
turn profits from the elimination of Dick 
spoiled on account of leaky roof. 


We are very glad to recommend 
Celotex as insulation for this class of 
construction.

Gentlemen: 


I have used Celotex for roof in- 
sulation under my roofing on many puildings 
in Chicago and its environs. 


- Celotex is the best roof insula- 
tion I have used for the following reasons: 


lst. It comes in sheets of large 
area and, therefore, can be handled by 
roofers according to their usual method. 


2a. It is of more uniform 
thickness than any other roof insulation 
I have handled. 

ica It has a hard surface, so ; 
that the roofing pitch can pe applied to it 
and the roofing paper applied thereto 
without any unusual absorption of pitch, 
which is a great fault of other insulating 
materials. 


It has a high insulating value, 
because I have used it on some very par-— 
ticular jobs where the problem of ceiling 
condensation is very severe and it gave 
great satisfaction in these cases. 


Furthermore, it is a board of 
stiff texture, so after the roofing pitch 
and gravel are applied on the roof over 
the Celotex insulation a man can walk over 
the roof without danger of puncturing the 
paper, whereas if softer insulations are 
used this would occur. 


On the whole, I will say that 
Celotex is the most satisfactory roof in- 
sulation I have ever seen. 
Very respectfully yours,

Gentlemen: - 


Replying to your letter of re- 
cent date requesting an expression from us 
as to the merits of Celotex for plaster 
and stucco base, we are pleased to say 
that it has given us very good results. 


We first tried it out ona 
bungalow for Mr. Ira Howe on Brownell 
Avenue, east of Collins Road, as a plaster 
base on outside walls. Not a single crack 
developed on either the brown or finish 
coats of plaster on these walls, whereas 
the interior walls which were regularly 
lathed had their usual quota of buckles and 
cracks. During the zero weather, the out- 
side walls of this house were just as warm 
as the interior. 


We also used it as a plaster 
base on a residence erected for Mr. J. P. 
Chambers on Highland Avenue, west of 
Collins Road. The results were the same. 


We have also used it as a stucco 
base at Nos. 600 and 602 Atlanta Avenue. 
Not a single crack has developed. MThe 
house at No. 600 has already received the 
dash coat but at No. 602 it can be seen to 
best advantage the good results obtained 
bating Portland cement stucco on a Celotex 

ase, 


As it is our policy to build 
quality into homes instead of ascertaining 
the cheapest method, we have not thus far 
compiled any figures showing comparative 
costs. We believe it to be an article of 
exceptional merit and intend to continue 
using it for this reason alone.

HOW TO APPLY TT* 


PPLY Celotex directly to 

the studding of the build- 

ing, replacing wood sheath- 
ing—it shows greater strength— 
insulates. Apply it to the interior 
walls as a base for plaster, elim1- 
nating lath; plaster bonds per- 
fectly to its surface. Celotex on 
the roof not only insulates the 
building, but prevents conden- 
sation. Used as an interior or 
exterior finish it can be stained 
or painted in any color desired. 
In floor construction or partitions 
it is an effective sound deadener.
